Hi,
i'm playing a bit around with vcpus.
My guest is Windows 10 1903.
This is the excerpt from the config:
...
<vcpu placement='static' current='2'>4</vcpu>
<vcpus>
<vcpu id='0' enabled='yes' hotpluggable='no'/>
<vcpu id='1' enabled='yes' hotpluggable='yes'/>
<vcpu id='2' enabled='no' hotpluggable='yes'/>
<vcpu id='3' enabled='no' hotpluggable='yes'/>
</vcpus>
...
I'm able to hotplug vcpus, but when i want to unplug them i get the following:
virsh # setvcpus pathway 3 --live
virsh # setvcpus pathway 4 --live
virsh # setvcpus pathway 2 --live
error: internal error: unable to execute QEMU command 'device_del': acpi: device
unplug request for not supported device type: qemu64-x86_64-cpu
Does anyone know why it can't be unplugged ?
Sounds like qemu doesn't support unplug of vcpus. Which version of qemu
do you use?
